You have the right idea so far, but you forgot to finish it up.
Point slope form is
y - y1 = m(x - x1)
where m is the slope, and (x1,y1) is the point the line goes through. As you can see, we have infinitely many choices for (x1,y1). If you use the y intercept point (0,5), then
y - y1 = m(x - x1)
y - 5 = -1(x - 0) ..... this is one of infinitely many possible answers
OR
If you use the point (2,3), then we'd say
y - y1 = m(x - x1)
y - 3 = -1(x - 2) ..... which is another possible answer
There are infinitely many other choices, but I'm only picking the points in which your teacher has shown as big dots.
By the way, nice work on getting the correct answer for the slope-intercept form.
Yintercepts are where x=0
set to zero to solve
0^2+4y^2=16
4y^2=16
divide 4
y^2=4
sqrt both sides
y=+/-2
xintercept is where y=0
x^2+4(0)^2=16
x^2+0=16
x^2=16
sdqrtboth sides
x=+/-4
yintercepts are (0,2) and (0,-2)
xintercepts are (4,0) and (-4,0)
Answer:
The amount of money due to Beth-Ann at the end of this period is $27, 300.
Step-by-step explanation:
The amount at the end of a period, when simple interest is being charged is:
Amount (A) = Principal (P) + Interest (I)
Here interest is computed using the formula:

It is provided that:
P = 24,000
R = 11%
T = 15 months = 1.25 years
Compute the Interest as follows:


The interest earned is, <em>I</em> = $3,300.
Compute the amount of money due to Beth-Ann at the end of this period as follows:


Thus, the amount of money due to Beth-Ann at the end of this period is $27, 300.
Answer: Option B.

Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that

We know that when a = 28 then b = 7. So



Therefore the equation of proportionality is:

So when
then:
